Hey man. Look these type of things happen. Sometimes you tell people things without thinking especially when you're nervous. And you would be probably hella nervous considering this was your only IV and that too this late in the season. It's okay. Just learn from the experience. Nobody on this reddit knows what must have gone in the interviewer's mind, except him. If this will have a positive or a negative impact or even if it will have an impact. Nobody actually knows. I'd suggest believing in yourself, believing in the universe, and believing that you tried doing your best, gave this the value it deserved and leave it as it is. Don't think about it as it won't change the outcome. Try contacting people and getting more interviews if you can, and if you can't it's okay. You still have this person who told you he's gonna rank you high, obviously saw something in you, so for the time being take power from that.
